Tom Cotton, of the Independent Record, reports the Arizona Cardinals have signed LB Greg Carothers to a one-year contract, according to agent Chris Gittings. He recently played for the Amsterdam Admirals in NFL Europe. Gittings said the key for Carothers to catching on with the Cardinals will be versatility. He said that he will need to break in on special teams and could play either sam or middle linebacker. Due to his status as a NFL-Europe player, Carothers will not count against the Cardinals player limit until the final days of training camp.
